分析:
第一，划出定语从句和状语从句: that will propose making payments to witnesses illegal and willstrictly control the amount of publicity /that can be given to a case /before atrial begins.
第二，划出介词短语：In a significant tightening of legal controls over the press
第三，句子的结构分析:
(1)主干结构是主语(Lord Irvine含同位语the Lord Chancellor)+将来时谓语(will introduce)+宾语(a draft bill);
(2)that引导的定语从句修饰draft bill,其中，will propose 是第一个谓语，making payments towitnesses illegal是一个动名词短语做宾语，在动名词短语内部，payments towitnesses做making的宾语，illegal是宾补;第二个谓语是will strictly control, the amount ofpublicity是它的宾语。that can be given to a case before atrial begins是孕含有一个时间状语从句(before a trial begins)的定语从句，修饰publicity。
